A CORPORATION or NEW MACHINE FOR APPLYING LIQUID CEMENT OR OTHER LIQUIDS TO STOCK.

- Application filed A ril 23,

To all whom it may concern: 7

Be it known that I, Annnn'r E. JoHNsoN, a citizen of the United States, residing at Brockton, in the county of Plymouth and Stateof Massachusetts, have invented a new and useful Improvement in Machines for Applying Liquid Gement or other Liquids to Stock, of which the following is a specification.

My invention relates more particularly to machines intended to spread cement or other liquids over the surface of the soles of shoes or the surface of other articles, and my objects are as provide a liquid-spreading machine adapted to spread cement or other liquid evenly; to spread it in any desired thickness,- with. a minimum of waste; to spread it rapidly without. tearing or injuring the surface on which it is to be spread; to give capacity for spreading upon articles of greater size than the width of the spreading drum; to provide means whereby a portion only of a given surface may be coated at the highest possible speed and with the greatest degree of ease and safety. This I accomplish by the means which .I shall now cially adapted for spreading rubber cement upon the'soles of shoes.

The preferred embodiment of the inve n drawings, in which Figure 1 is a plan showing in dotted lines the position of a sole when having its slip only coated with cement; Fig. 2 is a side elevation looking in the direction of the arrow, Fig. 1; Fig. 3. is a cross-section of Fig. 1; Fig. 4 is a sectional view'of partof the drum and presser roll on an enlarged scale showing the shank part of a sole between of my improved drum partly roken away; Fig. 6 is a detail of the driving mechanism of the presser roll; and Fig. 7 is a sole with Referring to the drawings: 'On opposite sides of a vat or tank A adapted to hold the liquid to be spread, which, for convenience, I have supposed to be rubber cement and upon the frame of the machine, are bearings Specification of Letters Patent.

slight elevation above the main cement-carrying surface of the drum, that elevation depending upon the viscosity ofthe fluid to be spread and the thickness of the layer of the fluid'desired to'be deposited, as will be hereinafter explained. At about the middle portion of the length of this drum which is preferably formed of a suitable unyielding material, as cast-iron, its surface is cironmferentially grooved and has an annular ring or strip of felt or other suitable yielding, and preferably absorbent, material secured in said groove in such fashion that the outer surface of the felt is substantially flush withthe main cement-carrying surface of the'drum. This strip offelt is'marked d.

Above the drum .D is a presser roll F which has a smooth cylindrical surface adapted to bear upon the tops of the ridges E and is mounted upon a shaft G journaled in a comparatively long bearing H. This bearing H is carried on the upper side of a. plate I adapted to slide in a guide J formed in the frame of the machine, and so to allow the presser roll F to move away from the drum D when a sole or other article to be coated with cement is inserted between thedrum and the roll. The roll F is normally pressed toward the drum 1) by a spring K mounted on rod L, parallel withthe guideway, one end of the spring K abutting againstthe frameofthe machine, while the other end abuts against the head of the rod L, thereby allowing the spring K to be compressed as the roll F rises. A screw I, which enters a screw threaded aperture in the bottom of plate I and the head of which normally rests against the bed plate of the machine, serves as an adjustable stop to regulate the downward movement of the plate I.

It will be observed thatthe roll F is carried by a bearing'at one end of the rbll,

projecting from between the rolls'and thus used; that shown in the drawings consists of tight andloose pulleys, 1, mounted on the main shaft C, and a train of gears 2, 3, l, 5,

to transmitrotary motion from the shaft C to the parallel shaft G, the number of teeth on these gears being proportioned to make the presser roll F run properly in contact with the tops of the ridges E on the drum 1).

' will travel in the some direction.

table to deliver stock between the rolls.

To allow for the up and down motion of the shaft Gr caused by the rising and falling of the presser roll as different thicknesses of stock pass under it, the gear 4 is mounted on a. pin carried at the joint of two links 6, the other ends of which are journaled, one on the shaft G of the presser roll to which the hub of the gear 5 is fast, and the other on the'fixed stud 3, of the gear 3. The train'of gearing is so designed that adjacent surfaces of;the presser roll and the drum D It will now be understood that a sole or other article on which it is desired to spread cement be inserted between the drum and the presser roll, it will be seized between the presser roll and the ridges of the drum and drawn'through between them, the main cen'ient-carr ying surface of the drum lying close to the surface of the sole on which the cement is to be with it.

On the side of the drum from which the soles or other stock are fed is a, cover M to the vat ortank A, which serves as a feediig n the under side of this cover isa stripper plate l l' fastened in any suitableinanner. I prcfer to fasten this by screws passing through slots (I) in the plate in such manner that the stripper plateimay be fastened with its edge at any desired distance from the surface of the drum. This plate serves to strip off from the drumany excess of cement which might otherwise be carried up by it. A coverl on the delivery side of the rolls like wise tits close. Cross bars Q, Q, running from side to side of the vat on the delivery side of and parallel with the drum, Support thin Ways R /which are adapted to receive the sole or other cemented article after it has passed between the rolls; These ways are fixed with their points close to the surface of the drun'l, so that if thin stock is being cemerited, which might have a tendency to cling to the drum after passing the rolls, it

will he caught by the points of the ways and stripped off the drum. V v

The immediate object and advantage of mounting the presser roll so that it is supported entirely from one end, thus leaving the other end free, is two-fold, namely, to

seams spread but not in contact ing the slip so-called, to the outer sole. The slip covers only the fore part of the 1 outer sole, and it is undesirable, therefore, 1 to cement the shank. and heel part, both because of a waste of cement and for other ohvious reasons. In the-process'of securing the slip ti) the outer sole the outersole is run through the machine. sidewise (see Fig,

1), the heel and shank portions not passiiig through the machine. To accomplish this my construction is obviouslywell adapted, there being-no obstruction at the free end of the presser roll, so that the solemay be passed between the drum and roll 'sidewise,'-'

with the heel and shank portions projecting.

The drum of my new liquidrspreading ma chine is of peculiar construction, and the peculiarity of its construction resultsin peculiar advantages of operation.

My new'machine is primarily designed for spreading cementupon the soles of shoes in the process of manufacture, and while for those soles which have equal thickness in all parts, a drum the face of which is unyield- H19 in every pa rt would lay the cement proper. y, the fact is that it is common to skive off the sides of the shank part, and this skived portion does not, when a drum is em ployed, the entire face of which is unyieldmg, come into contact with the drum, being held out of contact by the thicker portions of the shank. My improved drum is designed to obviate this difficulty, and the re en t is accomplished by forming the far-eof the drum, about midway of the ion th of the drum, of felt or other suitable yieli terial. The preferred method of construction is that shown in the drawings, in which an annular groove is formed in'the face of and aroundthe drum, and a strip of felt of suitable length and thickness laid and'se cured within the groove.

When the sole is passing through the inachine, the fore and heel parts beingwider than the felt, lie across the felt and engage the unyieldin ling ma-' end portions of the drum,

while, when t e shank is passing between j the drum and the roll, the thick portion of the sl1a 1ikbe1ng narrower than the felt, is forced into the yielding felt, permitting the skived edges of the shank to be brought into contact with the felt or with the unyielding portion of the face of the drum, according to the Width bf the shank.
